A cable of a suspension bridge is in the form of a parabola whose span is 40m. The road way is 5m below the lowest point of the cable. If an extra support is provided across the cable 30m above the ground level. Find the length of the support if the height of the pillars are 55 mts.

The cable of a unformely loaded suspension bridge hangs in the form of a parabola. The roadway which, is horizontal and 72 mt. long is supported by vertical wires attached to the cable, the longest being 30 mts. and the shortest being 6 mts. Find the length of the supporting wire attached to the road-way 18 mts.from the middle.
